Explain how DNA is replicated within cells.

Interpretation Introduction

Interpretation:

DNA replication within cells is to be explained.

Concept Introduction:

 Nucleic acids are long, chain-like molecules consisting of repeating units called nucleotides. Each nucleotide has three components: a phosphate group, a sugar group and a base.

 The nucleic acids are classified into two forms which are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

 DNA contains the genetic material of living organisms. It consists of two complementary strands wrapped around each other, forming a double helix.

 DNA is self-replicating.

Explanation of Solution

DNA is self-replicating due to the complementary nature of its base units. During cell division, DNA forms two complementary daughter strands exposing the individual bases...
